Forms

ameaçar (first-person singular present ameaço, first-person singular preterite ameacei, past participle ameaçado)[1] The Cantigas de Santa Maria have both ameaçar (also spelt amẽaçar) and meaçar;[2][3] Cunha dates both to the 13th century.[2][3] Houaiss adds ameeçar and amecar from the 14th century.[4] Feijó (1734) sets the spelling ameaçar against the form amiaçar.[5]

Etymology

It is formed from Portuguese ameaça + -ar.[4][6][7][8] Wiktionary also allows a Vulgar Latin verb *admināciō (“to threaten”), built on *mināciō.[1]

The noun ameaça, of the 13th century in its older form Old Galician-Portuguese meaça, is from Vulgar Latin minācia (“threat”) with the feminine article fused to it.[9][3] The Latin noun, which Plautus already used beside minae (“threats”), is formed on mināx (“threatening”).[10][1] Houaiss derives the adjective from minor (“to jut out; to threaten”), the OLD from the plural noun for threats.[9][11]

The Romance verbs Galician ameazar, Spanish amenazar, Catalan amenaçar, French menacer and Italian minacciare, and the English word menace, belong with it.[1]

Earliest recorded meaning

Machado and Lorenzo quote a Latin law text of 1202 with the Romance verb in it: homine de fora qui in sua quintana ueneris amenaçar “a man from outside who comes to threaten in his farmstead”.[6][2] In Galician-Portuguese the verb is common in the Cantigas de Santa Maria: one is headed como Santa Maria ameaçou o bispo “how Holy Mary threatened the bishop”, and another tells how the devil threatened the painter de o matar “to kill him”.[2] A cantiga d'escarnho complains of a man who de mais m'ameaça “threatens me besides”.[12]

Semantic evolution

The medieval senses were already “to threaten someone” and “to threaten to do something”: in the Graal Queen Guinevere is threatened with death, and a 1383 document says o dito priol os ameaçaua “the said prior threatened them”.[2][6] Morais (1813) adds the impersonal sense “to be imminent” (o mayor damno que ameaçava) and things that threaten, such as a rock at sea.[13] Vieira (1871–1874) adds making a threatening gesture and showing the symptoms of a disease.[14] The catenative use, ameaçar cair “to be about to fall”, and the sense “to endanger” complete the modern range.[4][1]
